This week I had to do water fillter and how to take out all the bacteria in it.
First I had to get the items to make a water filter. The items are a clear bottle that is cut from the middle part near the lid cottan balls, sand, and pebbles. So I had to put cottan balls at the bottom of the bottle sand obove the cottan balls and pebbles at the top.
Next The dirty water goes through the pebbles that are catching the bigger pieces that are in the dirt water. Then the dirty water goes through the sand which is trapping all the little pieces of bacteria in it. Last the dirty water gets sucked up by that cottan balls which is sucking up all the bacteria in it to make clean water.
Lastly I had to write how a filter works and make my own kind of fillter just by useing those items. I enjoyed this task because now I know how to make a water filter but I suggest after the water comes out you should boil it to make it clear because somtimes it doesent come out clean so I suggest boiling the water before you drink it.
